3 Claims. c1. 57-125 This application constitutes a division of myapplication Serial No. 218,732, filed August 22, 1962.

This invention relates to travelers having a wear resistant element ofthermosetting material of predetermined contour pre-molded on areinforcing wire and then the plastic traveler molded upon the insert ina manner to expose at least part of the wear resistant element in thelarge hook end portion of the traveler.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters and, in which, the drawing illustrates an enlarged side viewof a traveler embodying my invention, with part of the construction insection in diagrammatically illustrating the traveler with a wearresistant element therein.

In the accompanying drawing, I have illustrated one adaptation of atraveler. In the drawing, represents the shank of the traveler having asmall book end 11 and a large hook end 12 joining the shank in a roundedportion, as at 13. The body of the traveler is formed from moldedplastic material, as indicated by the sectional portion thereof, and anysuitable type of material can be employed such, for example, as nylon,Delrin or the like.

At 14 I have shown a more or less hourglass form of wear resistantelement by virtue of the rounded recessed central portion 15 and theextended larger diameter ends 16. The recessed portion 15 forms at theinner portion of the rounded part 13 of the traveler, Where it isexposed, the desirable wear resistant surface in the resulting traveler.

In constructing my device, the element 14 is pre-molded upon a wire orsimilar core 17, with the ends 18 of the core extending beyond the ends16 of the element 14, as clearly illustrated, so that, in formation ofthe resulting traveler, the insert element 14 can be positioned in themolds forming the traveler proper by the use of supporting pins 19,recessed, as seen at 20, to receive the ends 18 in definite location ofthe insert element 14 in the molds, preparatory to forming the travelerupon the insert 14, in the manner illustrated, so that surfaces 21 and22 of the hook end 12 of the traveler will properly aline and registerwith the surface of the recess 15 for exposure of the resistant elementin the manner clearly shown. It will be understood that, in the presentillustration, the pins 19, which are actually core pins, are in theposition they assume in the mold which forms the traveler and these pins19 are withdrawn from the traveler in the operation of removing thetraveler from the cavity of the molds forming the same and this removalwill leave in the traveler apertures, as at 19.

It will, further, be apparent that the contour of the insert element 14definitely positions the element in the traveler body and that thesurface of the recessed portion 15 of the element is exposed to sides ofthe rounded portion 13,.as diagrammatically illustrated, in part, by thedotted line 23. In the construction illustrated, the element 14 isformed of thermosetting rubber, or rubber compositions, synthetic orotherwise. However, any type and kind of thermosetting plasticsproviding Wear resistant properties can be employed.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A traveler comprising a molded plastic body having a hook end, a wearresistant element of thermosetting plastic material constituting aninsert in said hook end for exposure of part of the element on innersurfaces of said hook end, said element including a wire [reinforcementon the axial center of said element with an end thereof projecting fromsaid element and thus forming a pin end, and said pin end of the elementproviding a means for positioning of the element in the hook end portionin the process of molding said traveler.

2. A traveler as defined in claim 1, wherein said pin end constitutespart of said reinforcement and is arranged longitudinally of saidelement.

3. A traveler comprising a molded plastic body having a hook end, a wearresistant element of thermosetting plastic material constituting aninsert in said hook end for exposure of part of the element on innersurfaces of said hook end, said element including a continuous wirereinforcement passing through the axial center of said element with theends thereof projecting from said element and thus forming pin ends, andsaid pin ends of the element providing means for definite positioning ofthe element in the hook end portion in the process of molding saidtraveler.
